Pour the batter into the prepared pan. Mix together the sugar and cinnamon, and sprinkle over the batter. Bake for 60-75 minutes, until a toothpick inserted in the center comes out clean.
Don’t pack the flour in the measuring cup. Scoop it and level it off with a knife instead. I don't normally do this when baking, but the recipe highly recommends doing this because it does makes a difference in this recipe
